IBOILER.

Application filed April 28, 1923, Eleral No. 633,968, and in FranceApril 27, 1922.

My invention relates to a low-pressure boiler adapted chiefly l'or hotwater or steam heatingl purposes, and designed 'so as to be simply andeconomically constructed, the heating power of the boiler beingconsiderable with respect to its small size and light weight.

The walls of the said boiler comprise a plurality of hollow verticalpanels of east iron which are not in direct communication with eachother, but are connected together at the top and bottom by transversecollectors. Each ot the said panels has the forni of l flat receptaclewhich is closed on all sides except for two apertures or nipple openingsthrough the inner wall thereot for connecting the same with the saidcollectors.

The upper collector constitutes the dome et the furnace, and it has anopening` therethrough for the escape of the products of combustion tothe chimney.

The lower collector` constitutes the bottom ot` the ash pit.

The appended drawing.,r shows three consti-notional forms oit' boileraccording to the invention.

Fig. l is a vertical section ol the lirst form of? construction.

Fin'. 2 is a cross-section on the line ill-A. of Fig. l. l

Fig'. 3 is a horizontal section of a torni of construction.

Fig. l is a vertical section of the third 'lorm ol construction.

igure a top view, (the cover'plate being removed) parts being; breitenaway.

lnihe device shown in Figs. l and il, the walls ol? the boiler areformed oit tour vertical panels nl u? nfl c* having the shape et lintreciupllules, each being' cast in :i single piece. ln order to provide astronger construrtiini, the inner and outer faces of each receptacle orpanel may be braced by the est cross-pieces o. At o and (Z.- areindicated two transverse collectors whereof one forms second the dome ofthe furnace and the other the panels al a2 a at by the unions e whichare analogous to the members used to conneet radiator' elements, or byfiat connecting,` members such as flanged connections bolted in place..

The apertures j' and y are formed in the outer panel; the upper apertureserves for the fuel inlet and is provided with the cover fr; the loweraperture is provided with the aslrpit door j. On the other hand, aconduit /lt is provided in the collector c ior the discharge ol. smoke.The hot water inlet and outlet can be disposed upon the panels or uponthe collectors. Ribs or wings of greater or less height are preferablyformed upon the inner and outer face of the panels in order to augmentthe transmission ot' heat.

ln the example shown in Fig. 3, each of the lateral faces of the boilercomprises two panels a2 and two panels at. The boiler shown in Fig. 4Lhas at the rear an additional panel 0:5 which forms with the panels a3 avertical flue which conducts the smoke from the upper aperture m to thelower aperture fn. which is intended to be connected with the chimney.

l claim:

A boiler comprising a plurality of separate, hollow panels forming thevertical walls thereof; the lower portions of said liollow panelsforming the vertical wall portions ot the ash-pit, an opening inthelower portion of one of said hollow panels to permit ol' access to saidash-pit, a hollow meinber engagi.ng the uppe portions of said hollowpanels and constituting the top of said boiler, a` hollow panel memberdisposed interi'nediate oie and in engagement with the ash-pit portionsoit said` panels below said openingv and forming the transverse' bottomwall ot said ash-pit, and communica tingl connections between each ofsaid panels and said members serving to secure the saine together,substantially as speeiied.

ln testimony that I claim the foregoing as my invention, I have signedmy name.
